For those who are not familiar with the area, Rocksprings is county seat of Edwards county (more than twice the size of  Rhode Island—2,120 square miles vs. 1,045 square miles.  Rhode Island has 200 people/ sq. mi. and Edwards County has only one/sq. mi.). 

 

 

 

Only two aquatic troglobites are known from the western Edwards Plateau. The amphipod Stygobromus hadenoecus has been found only in the Devil’s Sinkhole, Edwards County. The only other aquatic species is the isopod Cirolanides texensis. This species is known from O-9 Well, Crockett County; Cave Y, Scheicher County; and Devil’s Sinkhole, Edwards County. It probably will be found in most deep caves containing permanent streams and lakes.
